There just isn't any meaningful space left in T3, unless they plan on taking over one of the third-party lounges. That's a lot easier said than done, and there's the question of what they'd do with a small, awkward, "satellite" lounge.

Until T5 opens in the next decade, I don't see any meaningful improvement to SQ's lounge situation. They could of course assign more peak hour flights to T2, but then the lounge situation there is similarly dire.
